test(web): align auth e2e with console home

[lyzno1]

Summary

• Align auth/default-entry E2E semantics with the console home route (/) instead of forcing /apps through redirect_url.
• Keep /apps as the Studio/apps-console surface and add a separate reusable waitForConsoleHome helper for the default console entry.
• Add an E2E session-refresh scenario that removes the access token, keeps the refresh token, verifies /auth/refresh?redirect_url=/, and lands back on console home.
• Add focused web unit coverage for NormalForm default post-login fallback to / and basePath-aware /auth/refresh behavior.

Verification

• pnpm -C web test app/signin/__tests__/normal-form.spec.tsx app/auth/refresh/__tests__/route.spec.ts
• pnpm -C e2e type-check
• pnpm -C e2e e2e:middleware:up
• E2E_START_AGENT_BACKEND=0 pnpm -C e2e e2e -- --tags '@smoke and not @fresh and not @skip'
• E2E_START_AGENT_BACKEND=0 pnpm -C e2e e2e -- --name 'Refresh the console session during server-side navigation'
• vpr lint --fix --quiet
• git diff --check
